Brief Description

Downloader.TPG is a Trojan, which although seemingly inoffensive, can actually carry out attacks and intrusions.

It uses stealth techniques to avoid being detected by the user:

It deletes the original file from which it was run once it is installed on the computer.

It uses several methods in order to avoid detection by antivirus companies:

It terminates its own execution if it detects that it is being executed in a virtual machine environment, such as VMWare or VirtualPC.

The means of transmission used include, among others, floppy disks, CD-ROMs, email messages with attached files, Internet downloads, FTP, IRC channels, peer-to-peer (P2P) file sharing networks, etc.
